Can we please be clear that this WASN'T A DENTIST, IT WAS A VETERANARIAN TRYING TO BE A DENTIST. There is a big difference. Give your dog or cat hard food and chews and bones to keep their teeth clean.

And please be sure to give your dogs GOOD bones - beef bones that have not been cooked/boiled, or bully sticks. Rawhide is hard on their digestive system and cooked bones can splinter and kill a dog.
